LYMAN V. SOUTHWORTH, OF NEWPORT, MICHIGAN.

,IMPROVEMENT IN CLOVER THRASHER AND HULLER.

Specification forming. part of Letters Patent No. 20$,210, datedSeptember 17, 1878; application filed December 8, 1877.

To all whom it may concern:

Be it known that I, LYM AN V. Sonrnwonrn, of N ewport,in the county ofMonroe and State of Michigan, have invented a new and useful Improvementin Clover'Elullers; and I do declare that the following is a true andaccurate description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, and beingapart of this specification.

The nature of this invention relates to an improvement in theconstruction of cloverhulling machines and the invention consists in thecombination and arrangement of the picker, shaking screens with solidbottoms, and the concave, as fully hereinafter explained.

Figure 1, Sheet 1, is a perspective from one side of my machine, showingarrangement of carrier and means of operating the adjustablepickerboard. Fig. 2, Sheet 2, is a perspective from the opposite side ofthe machine. Fig. 3, Sheet 3, is a longitudinal section through thecenter.

In the drawings, A represents the frame of my improved clover-hullingmachine, at one end of which is journaled a spiked cylinder, B, which isdriven by a pulley, a, on one end of its shaft. On the other end of theshaft is another pulley, a. Beneath the cylinderB is located anadjustable spiked concave, O, pivoted at its lower inner corners to theframestandards. The concave G is raised or lowered by means of theeccentric-shaft G, which is journaled just below it, and operated fromthe outside by a crank, c, which is held in position by any convenientmeans.

Immediately in the rear of the cylinder 13 is suspended the perforatedshaker D, consisting of a screen, 61, and the solid floor d, inclosed byproper sides.

To the bottom of the shaker D is attached the rod (1 which is connectedwith the doublecrank shaft E, journaled at e, in the frame A. This shaftE has upon one end a pulley, e, and on the other a crank, 6

At the rear end, and above the shaker D, is journaled the cylindricalpickerF, one end of the shaft of which passes through the upper end of aconveyer, G, and has upon its outer end, beyond the conveyer, a pulley,f. In the rear of this picker F is located the concave screen H, whichextends under the picker, from below the screws on the shaker D, nearlyto the top of the frame. In the rear of this concave screen is suspendedthe shaker I, construct-ed in the same manner as the shaker D, buthaving its bottom inclined forward toward the hulling-cylinder J, andactuated by the shaker-rod *5, one end of which is connected to thecrank-shaft E and the other to the floor of the shaker I.

The boiling-cylinder J is journaled in the frame A at j, and has uponone end of its shaft the driving-pulleyj and at the other end has alarge pulley, 3' and outside of that a smaller pulley, j.

Beneath the hulling cylinder, and almost in contact with it, is placedthe rasp concave K. In the rear of thehulling-cylinder is suspended theshoe L of the fanning-mill, provided with suitable screen and aninclined bottom. At the end of the shoe is the spout M, which emptiesinto the lower end of the conveyer G, which is pro vided with a properbelt and cups for raising such particles as may fall into it. The shoe Lis provided with a regulator, m, which is pivoted through the sides ofsaid shoe at its rear end, beneath the upper screen, and in front of thetrough, and is controlled by the crank m.

To the side of the screen M is attached, by means of a staple, the roda, which engages with a bell-crank, 0, pivoted to the frame A. To theother end of the bell-crank is attached the rod 02, which engages withthe crank on the end of the double-crank shaft E. In front of the shoe Mis located a fan, which is driven by a pulley on the outer end of itsshaft.

In front of the cylinder B is the hopper P, which is hinged to the frameA at 1), so that it can be folded back, exposing the cylinder andconcave board.

In operation, the clover to be thrashed is fed in between the cylinder Band concave G, by the teeth of which it is thrashed; thence it allpasses onto the shaker D, and the cloverseed falls down through thescreen and is com veyed to the hulling-cylinder. The straw then passesunder the picker, which picks it and passes it over the concave screen Hupon the shaker I, where the balance of the seed falls through thescreen into the shakerfloor, and

is conveyed to the hulling-cylinder, while the straw passes on out ofthe machine.

The seed from the two shakers passing through the hulling-cylinder, thehulls are rubbed off of the seed, and the seed and chaff are thrown uponthe screen of the fanningmill, from whence the chafi is blown out, whileclean seed falls through the screens onto the bottom of the shoe of thefarming mill, and from thence passes down into any proper recept-acle.

The seed which passes the hulling-cylinder without being hulled passesover the screens and falls into the trough M, from whence it passes intothe elevator G, which carries up and delivers it through a spout to thehullingcylinder.
